Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed i ai 27. 1907. semi No. 370.666.

T 0 all whom it may concern:

Be it known that I, ERNEST BLACKFORD, a citizen of the United States,residing at P0- tomac, in the county of Vermilion and State of Illinois,have invented a new and useful Revolving-Paddle Churn, of which thefollowing is a specification.

This invention relates to churns and has for its object to provide acomparatively simple and inexpensive device of this character in whichthe dashers are mounted on telescopic shafts and arranged to rotate inopposite directions.

A further object of the invention is to provide means for connecting thedasher-carrying shafts with the operating means.

A still further object of the invention is to generally improve thisclass of devices so as to increase their utility, durability andefficiency as well as to reduce the cost of manufacture.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

In the accompanying drawings forming a part of this specification:Figure 1 is'a longitudinal sectional view of a churn constructed inaccordance with my invention. Fig. 2 is a top plan view of thesupporting bracket. Fig. 3 is a transverse sectional view taken on theline 3-3 of Fig. 1. Fig. 4 is a front elevation of the catch for holdingthe cover in closed position. Fig. 5 is a perspective view of the socketcarrying member. Fig. 6 is a similar view of the squared end. of theadjacent member.

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

The improved device forming the subject matter of the present inventionincludes a receptacle or body portion 5 preferably cylindrical in shape,and formed of metal, wood, porcelain or other suitable material, saidreceptacle being provided with a removable cover 6 having a dependingflange 7 for engagement with the interior walls of the receptacle, asshown.

Mounted on the cover 6 is a supporting bracket having its intermediateportion curved laterally at 8 and its opposite ends bent to formlaterally extending lugs 8 and 9 one of which is secured to the top ofthe disposed paddles churn in any suitable manner as by screws orsimilar fastening devices 10. Secured to and preferably formed integralwith the supporting bracket are laterally'extending arms 11 the ends ofwhich are bent to form lugs similar in construction to the lugs 8 anddesigned for attachment to the cover 6. Arranged within the receptacle 5is a vertically disposed shaft 12 having its lower end journaled in astep bearing 13 secured to the bottom of the receptacle and its upperend provided with a squared recess or socket 14 for the reception of thereduced extension 15 of a short shaft section 16. Surrounding the shaft12 and loosely mounted for rotation thereon is a hollow shaft 17, thelower end of which terminates short of the bottom of the receptaclewhile the upper end thereof is provided with a squared shoulder 18adapted to engage a correspondingly shaped socket 19 formed on the lowerend of a short tubular member 20. The shaft section 16 extends throughan opening in the supporting bracket and is provided with a beveled gear21 which meshes with an intermediate beveled gear 22 journaled on a stubshaft 23 extending laterally from the curved portion of the supportingbracket, as shown. The intermediate gear 22 meshes with a beveled gear24 secured to and preferably formed integral with the tubular member 20.The

beveled gear 24 meshes with a master gear 25 journaled on the laterallyextending lug 9. Secured to and extending laterally from the shafts 12and 17 are a plurality of radially or dasher blades 26 which revolve inopposite directions and serve to churn or agitate the liquid in thereceptacle 5 when the master gear is rotated. It will thus be seen thatby rotating the handle 27 motion will be imparted to the master gear 25and through the medium of the beveled gears rotate the paddles ordashers in opposite directions. Pivotally mounted on the cover 6 arelooking members 28 having their free ends formed with recesses 29adapted to receive suitable ears 30 extending laterally from theexterior walls of the receptacle thereby to lock the cover in closedposition. As a means for centering the operating shaft with respect tothe interior walls of the receptacle there is provided a transverse bar31 the opposite ends of which are seated in notches or recesses formedin brackets or supports 32 secured to the adjacent walls of thereceptacle, as shown. It will thus be seen that by releasing the lockingmembers 29 and elevating the cover 6 the shaft sections 16 and 20 may bedisconnected from the shafts 12 and 17 so that the dashers may bereadily removed from the body of the In order to assemble the par-ts itis merely necessary to insert the squared shoulder 18 in the socket 19and then introduce the extension 15 of the shaft section 16 in the adjacent socket or recess 14 When the operating shafts 12 and 17 Will beoperatively coupled With the operating mechanism, as Will be 1 readilyunderstood.

From the foregoing description it Will be seen that there is provided anextremely simple, inexpensive and efficient device admirably adapted forthe attainment of the ends in view.

Having thus described the invention What is claimed is:

A churn including a receptacle having supporting lugs secured to theinterior Wall thereof, a bar extending transversely across thereceptacle and engaging said lugs, a cover, a vertically disposed shaftarranged l Within the receptacle and extending through the bar, atubular shaft surrounding the vertically disposed shaft and alsoextending through the bar, dashers carried by the ver- ,tical andtubular shafts a supporting bracket churn and thoroughly cleaned Whendesired.

secured to the cover, a shaft section journaled in the supportingbracket and operatively connected With the vertically disposed shaft, atubular member surrounding the vertical shaft and operatively connectedwith the tubular shaft, beveled gears carried by the shaft section andtubular member respectively, an intermediate gear journaled on thebracket and meshing with the beveled gears, and a master gear mountedfor rotation on the bracket and engaging one of the beveled gears, theopposite beveled gear being free to rotate independently of the mastergear.

In testimony that I claim the foregoing as my own, I have heretoa'llixed my signature in the presence of two Witnesses.

ERNEST BLACKFORD.
